A Comprehensive Choice of Vented & Unvented Cylinders
BES supplies vented and unvented cylinders. Our vented copper cylinders are grade 3 with a maximum working head of 10m, 25mm standard insulation, and large heating coil. They comply with Part L Building Regulations. The unvented stainless steel cylinders are able to withstand mains pressure. Unvented hot water cylinders are WRAS, WRc-NSF, and BEAB approved, with each cylinder being pressure tested to 15 bar.
Vented cylinders are a popular choice for gravity-fed systems, using a cold water storage tank to supply hot water at low pressure. Our range includes direct vented cylinders and direct vented stainless steel cylinders for enhanced durability. We also stock indirect vented copper combination cylinders, which use an external heat source like a boiler, as well as indirect vented stainless steel cylinders and indirect part L copper cylinders, all designed to meet modern efficiency standards.
Unvented cylinders provide high-pressure hot water directly from the mains, delivering improved flow rates and eliminating the need for a storage tank. At BES, we offer a selection of unvented direct cylinders for electric heating and unvented indirect cylinders that integrate with a boiler. Our range also includes essential accessories like expansion vessels, pressure relief valves, service valves, and tundishes to ensure system safety and efficiency. For trusted performance, explore our Stelflow Direct and Stelflow Indirect unvented cylinders, which are known for their robust construction.
A reliable cylinder flange is crucial for preventing airlocks and ensuring optimal water flow. We stock brass cylinder fittings, Essex cylinder flanges, and a variety of flange options to suit different installation needs.
For those looking to heat water independently of a boiler, our immersion heaters are an excellent solution.
